PP sheet is a kind of semi-crystalline material, which is also called polypropylene sheet. It is more complex than PE and has a higher melting point. They are used in acid and alkali resistant equipment, environmental protection equipment, wastewater, waste gas discharge equipment, washing towers, clean rooms, semiconductor plants and related industrial equipment, and the first choice for manufacturing plastic water tanks. Among them, PP thick plates are widely used in stamping plates. , Punch mattress board and so on.

PP board is a high polymer, semi-crystalline material. It has a very lightweight, uniform thickness, smooth surface, very flat surface, good heat resistance, high mechanical strength, and very stable chemical properties. PP boards are used in chemical, electronics, construction, food packaging and water treatment, and even machinery fields. What are the applications of PP boards? Here is a brief introduction to help you deepen your understanding.
1. The billboard used for advertising, you may also often use the small white blackboard, which is made of this material;
2. Recycling boxes, such as cartons, packing boxes and stationery boxes, are mostly made of PP board;
3. Industrial boards, such as cables and wires and outer packaging materials of various commodities, even pads, bottom plates, etc.;
4. The electronic field is also widely used. For example, packaging materials for electronic products and other antistatic or conductive materials are made of PP boards.
5. Industrial exhaust system, used for the connection of exhaust gas purification equipment and gas discharge.
PP sheet is a kind of sheet we often use. It has low density, is easy to weld and process, has superior chemical resistance, heat resistance and impact resistance, non-toxic, and odourless. It is currently one of the most environmentally friendly engineering plastics. So do you know how to weld a PP sheet? Do you know what the welding methods of PP sheet are?
The welding method of PP sheet is generally considered that thermoplastic welding is irreversible. A few processes, such as induction welding, can produce reversible assemblies. The way to choose should be selected in the design of the part because the welding method is critical to the needs of the part description, and different welding methods have other effects.
Hot gas welding technology is generally used for welding plastic pipes, sheets or semi-finished products rather than injection moulded parts. However, many thermoplastic moulded components, in common, are that the thermoplastic automobile disc is repaired by hot-gas welding technology, and hot-gas welding is sometimes used to prepare plastic-like moulded parts.
Hot plate welding is a thermoplastic welding process in which the metal mould is heated by electricity to soften the connected plastic part's surface. Applicable to almost all large or small thermoplastic parts. Commonly suitable for welding softer semi-crystalline thermoplastics such as PE plates or PP plates. Since different mould surface temperatures can be used for two other thermoplastic materials, this process is most suitable for welding dissimilar materials. Hot plate welding can reach high welding strength. But the cycle of this process can be relatively long, 15s for small parts and several minutes for large amounts.
Hot gas welding is a welding method widely used to connect thermoplastic profiles and sheets to produce large parts. It is suitable for the manufacture of smaller injection-moulded parts, thermoplastic parts, and sample moulded parts that require some assembly. It is essential to produce welding rods with the same polymer brand as the parts being welded.
